Frequently Asked Questions (FAQs) – Prestressing Bridge Projects
What does a prestressing bridge contractor do?
A prestressing bridge contractor specializes in designing and executing prestressed concrete structures, including bridges, flyovers, and culverts. Services include tendon installation, post-tensioning, bridge launching, grouting, bearing installation, concreting, and shuttering, ensuring long-lasting and safe infrastructure.
How does prestressing improve bridge strength and durability?
Prestressing introduces compressive stress into concrete to counteract tensile forces. This reduces cracking, improves load-bearing capacity, increases durability, and lowers maintenance costs over time.
What is the difference between pre-tensioning and post-tensioning?
- Pre-tensioning: Tendons are tensioned before casting concrete, commonly used in precast bridge components.
- Post-tensioning: Tendons are tensioned after concrete hardens, ideal for flyovers, long-span bridges, and in-situ construction.
Is post-tensioning suitable for flyovers?
Yes. Post-tensioning allows longer spans, optimised load distribution, and faster construction. It is widely used in urban flyovers, elevated corridors, and highway bridges across India.
Why is prestressed concrete preferred in bridge construction?
Prestressed concrete offers higher structural strength, reduced deflection, longer lifespan, and efficient material use, making it ideal for flyovers, bridges, and culvert projects.
What are the key services offered by a prestressing contractor?
JSR Prestressing provides:
- Bridge prestressing and post-tensioning
- Bridge launching and girder erection
- Cement grouting and bearing installation
- Precision concreting and shuttering systems
